maximums shown in the “Characteristics ". Such as CP5050,these are (1) 30 Apeak
for continuous input and (2) 50 Apeak for pulse widths 10 μs. (1) indicates an upper
waveform response limit of 30 Apeak. Use the sensor at RMS current input levels
that are within the rated continuous maximums. (2) indicates the upper response
limit for a single input pulse.
When opening the sensor head of the probe, be sure to operate with the opening
lever. If an upper core is forced to open when the sensor head is locked, the open-
close mechanism can be damaged.
Preparations for Measurement
：
1
）
Have the power supply and oscilloscope ready for waveform
measurement ready.
2
）
CP8000A series connects the power supply
，
the red LED lights.
Range select and Degauss AutoZero
：
1
）
With the oscilloscope input at ground, adjust the trace to the zero position.
2
）
Set the input coupling of the oscilloscope to DC.
3
）
Connect the output connector of the current probe to the input connector of
the oscilloscope. Turn the collar until it clicks, and check that it is locked
securely.
4
）
Without clamping the conductor to be measured, press the opening lever
until the "UNLOCK" indication disappears, and check that the sensor
head is properly closed.
5
）
Select appropriate “Range” via the Range Key.
6
）
Press the “Degauss AutoZero” key, if succeed,continue to next step. If
failed,make sure the probe locked or other problems.
Making the Measurement
：
1
）
Check that the system is safe and that the preparations described in the
preceding section have been carried out.
